A thread is wrapped around a cylindrical spool, of radius R = 2.0 cm, whose central axis is fixed on a support. Somebody’s hand pulls the thread off the spool. This causes the spool to rotate. The acceleration of the person’s hand is constant. Starting from rest, it takes 10 seconds for 5.0 meters of thread to be pulled off. What is the angular speed of the spool at time t = 2.0 s?
